7 Claims.

This joint application is an improvement on the copending soleapplication of one of the present applicants, Earl L. Schofield, SerialNo. 571,763, filed January 8, 1945, which was allowed September 6, 1946,but thereafter forfeited in favor of this application.

This invention relates to an improved bicycle stand of the well-knownkick type, so named because of its being adapted to be kicked up out ofthe way. The principal object of our invention is to provide anextremely serviceable stand of the kind mentioned which by reason of theuse of stamped sheet metal parts throughout the bracket portion, and thefact that the bent rod forming the pivoted supporting leg or prop isdesigned to be assembled in the bracket with its biasing spring withoutthe need for any drilling or tapping operations and without the need forany cotter pins, can be produced at much lower cost than other kick typestands now generally available.

Another important object of our invention. is to provide a stand of thekind mentioned which may be easily adjusted on the bicycle to the exactangle desired and then rigidly attached thereto in that position,without danger of its turning relative to the frame or changing itsangularity with respect to the frame, the stand being so designed tofacilitate the tightening of the bolts by eliminating any possibilityfor the nuts to turn, thus permitting the tightening of the bolts with asingle wrench.

The invention is illustrated in the accompany ing drawing, in which Fig.1 is a front view of a bicycle stand made in accordance with ourinvention, illustrated as applied to the rear fork portion of a bicycle,which appears in section;

Fig. 2 is a face view of the recessed swivel bear ing portion of thebracket;

In the kick type bicycle stand it has been common to provide a bracketsuitably clamped to the substantially horizontal spaced bars 5 of therear wheel fork, the bracket forming a support for the pivotedsupporting leg or prop. The present bicycle stand is of that type, andthe stamped sheet metal bracket 6, which pivotally supports the bent rodleg I for propping the bicycle, is fastened by means of a pair of bolts8 and clamping 2 plate 9 to the bicycle frame on the rear fork bars 5.

The bracket 6, in accordance with our invention, has the main bodyportion thereof stamped from a single piece of sheet metal to theflanged angular form shown, providing the substantially horizontal butarcuate clamping portion l0 and the recessed swivel bearing portion IIthat is inclined at a small angle from a vertical, as shown, theportions II) and H being integrally connected and rigidly'braced by thewide front and rear flanges I2. The arcuate top surface I3 is struck onthe radiusr, indicated in Fig. 1, and has line contact in substantiallyparallel lines with the bottoms of the bars 5 so that the bracket 6 maybe easily adjusted to different angularities with respect to the frameof the bicycle and yet may be clamped securely to the frame in any oneof its adjusted positions. The holes M for the bolts 8 are so spacedwith respect to the flanges 12 that the square nuts l5 threaded on thelower ends of the bolts 8 have surface to surface contact with the innersides of the flanges I2, as illustrated in Fig. 3, to prevent turning ofthe nuts and accordingly make it an easy matter to fasten the stand ontothe bicycle, it being only necessary to turn the head of the bolts witha wrench without paying any further attention to the nuts l5 after theyhave been started onto the bolts. Taking into consideration the factthat devices of this kind are often applied by boys and girls who aremore orfless mechanically unskilled, the advantage of this feature canbe better appreciated. The elongated slots 9a in the clamping plate 9through which the bolts 8 are extended permit shifting of the boltslaterally with respect to the plate 9 as required in the angularadjustment of the bracket 5 relative to the frame, the one side edgeportion 9b of the plate being curved downwardly, as indicated in Fig. 1,to conform to the curvature of the one bar 5 to locate the plate on theframe and resist sidewise or rotary displacement from its set position.The arcuate form of the clamping'portion-lll of the bracket 6 combinedwith the fact that there are two bolts 8 for clamping it on the frameeliminates any danger of the bracket 6 turning from a set position. Thearcuate form of the clamping portion l0 permits fastening of the bracket6 to the bicycle with a single bolt, if desired, the bolt being enteredthrough'a slot in plate 9 midway between slots 9a and through a hole inthe portion I0 midway between holes'M, without danger of the bracketturning relative to the frame about the single bolt as a center,However, if a single bolt is used the nut l5 used in connectiontherewith is preferably welded to the bottom side of the arcuate wall l3so as to obviate any difliculty due to the nut tending to turn when thebolt is tightened, and to avoid necessity for holding the nut with onewrench while tightening the bolt with another wrench.

The flanges l2 on the recessed swivel bearing portion ll of the bracketare much wider, as indicated at [6, in order to provide greater spac ingof the swivel bearings l1 and I8 for the rightangled bent upper end I9of the 'leg 1 an inner bearing plate being provided to provide thebearing hole l8 and being secured to "the inner edges of the flanges I2by entering lugs "2] that project from the flanges l-2 through slots 22in the plate 20 and bending these lugs at right angles, as clearlyappears in Fig. 4. The plate 20 is quite wide vertically in relation tothe bearing hole I 8 and has-outwardly bent end portions 23 which fitsnugly against the outer side of the flanges I2 to make for greaterstrength and rigidity, the lugs 21 being accordingly relieved of-acertain share of the bearing load. The por- "tion ll of the bracket iihas its web portion 24 subst'antiall'y comically recessed, as indicatedat '25, concentrically with the bearing hole I! and is recessed radiallywith respect to the recess 25 at 215 and T1, at points approximately 90apart, to loca'teathe-leg 1 in its lowered operative 'positionwhen-engaged in the recess 26 or in the raised out of the 'way po'sition"when'engaged in the recess 21, "asindicated in-dotted lines in Fig. -2.The bent pivot'encl 1-9 of the lag I has four radially "embossedportions 28 struck therefrom at circu'mfer'ntiailyspacd points '90-apart adjacent the inner bearing plate 20 and these embossed portionsdefine a shoulder 'annularly with resp'eci; to :the cylindrical rodmaterial of which the'leg lis made for support of the inner end ofacoiled compression 'springflQ, this spring being caged ion the bent end19 of the leg between the 'bearing 1'1 and the embossed portions "18. Itis not evennecessary to provide 'awasher as-a T58R13 for the winnerendof thespring 29, although, of course, one inay be provided if ade-=sired,*in which eve'ntit would doubtlesslybe unnecessary "to :provideas -*many embossed portions *28.

.In asseniblin'gthe spresent device the spring 29 is sh pped "over 'therod forming the leg r! from the bent-lower'end 30 athat -is adapted torest on the :sidewalk or other wsupportingsurface when the bicycle standis in use. The spring can be flexed enough to get it around the rightangle -bendontothe endzportion '19. The leg "I is then slipped throughthe bearing hole 11 and the spring 29 is "finally 'icomp'ressed againstthe bearing l 1 --when -the leg-1 reaches the assembled position "shown.There remains then only-the application ofthe inner bearingfplate 20 'tocomplete the assembly. Obviously, this constructioncan beproduced'atmuch'lower costithan others :now -genera/lly available,because of 'the' elimination of costly drilling and tappihg 0perati0nsand "the elimination of =coitteri pins which are :more or -less of anuisance so farias'assembling operations are concerned-and are likewise'a nuisance from the standpoint of hazard'to :the bicyclist, in addition-to being apt to get rusty and dropout, allowing other parts to becomedisassembled. The widespacing -of-the bearings Hand l8 eliminateslikelihood of binding even-though the-parts may nob be lubricated,asoftenoccurs. The important parts from the standpoint of maintainingthe stand in good operative condition, namely the spring 29 and nut l5,are more or less protected from the weather by the bracket 6.
